Problem: You are asked to design an air bag for a car. You know that the bag should be filled with gas with a pressure higher than atmospheric pressure, approximately $834mmHg(1\mathrm{.}097$ atm$)$ at a temperature of $23\mathrm{.}0C(295K).$ The bag has a volume of $54\mathrm{.}6L.$ What quantity, in $g,$ of sodium azide, $Na{N}_3$ should be used to generate the required quantity of gas?

$2Na{N}_3(s)2Na(s)+3N_2(s)$
